MESOSCALE DISCUSSION 0311
NWS STORM PREDICTION CENTER NORMAN OK
1245 PM CDT MON APR 07 2014
AREAS AFFECTED...SRN SC/SERN GA/NRN FL
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 071745Z - 071845Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...MODEST/GRADUAL AIRMASS DESTABILIZATION ACROSS THE
DISCUSSION AREA SUGGESTS THAT SOME INCREASE IN CONVECTIVE
INTENSITY/POTENTIAL SEVERITY WILL OCCUR AS CONVECTION MOVES INTO
THIS REGION. NEW WW MAY BE REQUIRED.
DISCUSSION...LATEST OBSERVATIONS AND OBJECTIVE ANALYSES SHOW GRADUAL
MOISTENING/DESTABILIZATION ONGOING AHEAD OF THE ADVANCING CONVECTIVE
LINE. MEANWHILE...A MODEST INCREASE IN REFLECTIVITY ALONG THE LINE
HAS BEEN NOTED OVER THE PAST HALF HOUR OR SO...ALONG WITH A COUPLE
OF BOWING STRUCTURES -- LIKELY IN RESPONSE TO THE IMPROVING
THERMODYNAMIC ENVIRONMENT.
AS CONTINUED DESTABILIZATION ENSUES...ADDITIONAL INCREASE IN
INTENSITY/ORGANIZATION WITH STORMS EMBEDDED WITHIN THE LINE APPEARS
LIKELY -- ALONG WITH A CORRESPONDING INCREASE IN SEVERE RISK. GIVEN
THESE FACTORS...A NEW WW WILL LIKELY BE REQUIRED ACROSS PORTIONS OF
THE DISCUSSION AREA.
